We know that a little over a century ago, in 1908, a comet struck Siberia in the Tunguska Event and it was devastating for the region, but because it was so remote and so little population that few were affected. Explorers took several years before they could even visit the site. There was no crater, but trees for miles around was flattened by the blast. If something similar had happened, 13,000 years ago by an even larger comet striking the glaciers in North America there’d be very little evidence to show for it today.

And even more recently in 2013 a meteor exploded over a populated Siberian city, Chelyabinsk, but because it was so much smaller than Tunguska the damage was relatively minor, 1100 were injured and thousands of windows destroyed.

I’m writing about it as a reminder to dig a little deeper to see if the evidence supports the theory. Catastrophic events have shaped human evolution and history, so it is possible, but is is true?

As a side note: It really should be the Year 12017 HE (Holocene or Human Era)
